The Boston Celtics have hired Brad Stevens as coach, stealing him away from a position at Butler that he appeared destined to hold for years to come.

Stevens will become the 17th coach in Celtics franchise history, the team announced Wednesday. Terms of deal were not made available, per team policy, but the Boston Herald reported that Stevens received a six-year contract and Yahoo! Sports reported the pact is worth $22 million.

"Our family is thrilled for the opportunity given to us by the leadership of the Boston Celtics, but it is emotional to leave a place that we have called home for the past 13 years," Stevens said in a statement.

Stevens takes over for Doc Rivers, who left to become coach of the Los Angeles Clippers. The Celtics will go from one of the NBA's longest-tenured coaches to a coach in his first NBA season as a head man.

He is not without experience, though. In his time with Butler, Stevens led the school to back-to-back appearances in the NCAA Tournament final. He was 166-49 in six seasons at the school, producing four Horizon League regular season championships and three tournament titles.

The Celtics are in the process of a rebuild, having traded franchise staples Kevin Garnett and Paul Pierce to the Brooklyn Nets. But they still have point guard Rajon Rondo on the roster, and, as SN's Sean Deveney was told, he will stick it out in Boston and does not plan to ask for a trade to a contender. Young forward Jeff Green and guard Avery Bradley also have potential.

"Brad and I share a lot of the same values," said Celtics president Danny Ainge in a press release. "Though he is young, I see Brad as a great leader who leads with impeccable character and a strong work ethic. His teams always play hard and execute on both ends of the court. Brad is a coach who has already enjoyed lots of success, and I look forward to working with him towards Banner 18."
